Rollable structure and electronic device using same

Abstract

A rollable structure includes an outer and an inner sliding rail. The outer sliding rail includes outer sliding blocks and outer shafts. Each of the outer shafts is fixed between any two adjacent outer sliding blocks. The inner sliding rail is movably clamped in the outer sliding rail and includes inner sliding blocks and inner shafts. Each of the inner shafts is fixed between any two adjacent inner sliding blocks. When axes of the outer shafts are aligned with axes of the inner shafts, the outer sliding blocks can rotate with the outer shafts as axes, and the inner sliding blocks can rotate with the inner shafts as axes. After the inner and the outer sliding rail move relative to each other, the axes of the inner and the outer shafts are misaligned, so that the outer and the inner sliding rail are in a plane.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 108122229, filed on Jun. 25, 2019. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUNDTechnical Field[0002]The present disclosure relates to a rollable structure and an electronic device using the same, and in particular, to a rollable structure that may be used to roll up or pull out and fix a display screen and an electronic device using the same.Related Art[0003]In an existing design, a screen display area of a small-sized mobile device is increased by connecting screens in parallel by using a plurality of devices, but the parallel connection manner results in seams among the screens. There is also a way of expanding a screen, but inconvenience in portability is caused. In addition, if a size of the mobile device is increased in the foregoing manners, an original int...

AI Technical Summary

Benefits of technology

[0010]Because the flexible screen may be rolled, bent and stored in the housing by using the rollable structure when not in use, the whole volume becomes as small as possible through rolling, bending and storage when the flexible screen is in a stored state, and a needed length of the flexible screen may also be shrunk as far as possible. When the flexible screen is to be used, the flexible screen may be pulled out and positioned by using the rollable structure, so that the flexible screen may be provided with a stabilization and positioning structure, to prevent the flexible screen from being prone to be rolled or be damaged by an external force during viewing and operating. Therefore, a display area as large as possible may be provided at a volume of the electronic device as small as possible, so that the user can enjoy experience of a broader vision on a small-sized mobile device.

Problems solved by technology

In an existing design, a screen display area of a small-sized mobile device is increased by connecting screens in parallel by using a plurality of devices, but the parallel connection manner results in seams among the screens.

There is also a way of expanding a screen, but inconvenience in portability is caused.

In addition, if a size of the mobile device is increased in the foregoing manners, an original intention of providing convenience in portability is lost.

However, there are no products for effectively protecting related structures of the flexible screen.

Even though the screen itself has light, thin, and flexible features, there is a problem in rolling, and the screen is prone to be rolled or be damaged by an external force when the screen is used as an independent product without a protection structure.
